In a group, the identity property is that each group contains an element, i, such that for all elements x, in the group, i*x = x*i = x. i is called the identity element.
In abstract algebra, a generating set of a group is a subset of that group. In that subset, every element of the group can be expressed as the combination (under the group operation) of finitely many elements of the subset and their inverses.
It is true, all are solids.
first group of periodic table... hydrogen is a gas and other elements are solid....
There is none. All of the elements in group/family in group IIA/2 are solids at room temperature.
nonmetals
No. Hydrogen, on a regular periodic table, is the first element in group 1, and it is part of the gas family.
Hydrogen is a gas, the other group 1 elements areliquid or solids at Standard Temp & Pressure
Which group on the periodic table contains chemical elements that are brittle as solids and cannot conduct electricity
It is the atomic number. It is the physical property.
a single group can have members that are solids, liquids, and gases and a single group can contain metals , nonmetals and metalliods both a and b
Chromium, Molybdenum, Tungsten and Seaborgium are all in group 6 of the periodic table. They are all classified as metallic substances. They are all solids a 298 K.
Most elements are metals and therefore solids. But there are many elements that are gases (oxygen O, Neon Ne, Argon Ar etc.) and two liquids which are Bromine Br and Mercury Hg
The element Rubidium is part of the alkali metals group and is silvery-white and soft. It has a melting point of about 40 degrees celsius and a boiling point of 696 degrees celsius. It can ignite randomly in air and reacts violently with water. It can form amalgams with mercury and its flame is a yellowish purple.
